A restaurant freezes a cherry and lime juice mixture to create slushes. Cherry juice costs $5 per quart, and lime juice costs $3
puteri [66]

Answer:

5c + 3(8 - c) = 36

Step-by-step explanation:

A restaurant freezes a cherry and lime juice mixture to create slashes. Cherry juice costs $5 per quart, and lime juice costs $3 per quart. Each day, the restaurant spends a total of $36 on 8 quarts of juice.  

Therefore, if there are c quart of cherry juice, then the number of lime juice is (8 - c) quart as the total number of quarts is 8.

Now, the total cost is $36 and therefore, we can write the equation to find the number of quarts of cherry juice is  

5c + 3(8 - c) = 36 (Answer)

Describe two ways to solve the equation 2(4x-11)=10
shtirl [24]
2(4x-11) = 10

On dividing 2 on both sides

\frac{2(4x-11)}{2} =  \frac{10}{2}

4x-11 = 5

On Adding 11 on both sides:

4x-11+11 = 11+5

4x = 16

On dividing both side by 4

\frac{4x}{4}  =  \frac{16}{4}

x = 4

Second way is:

We can use distributive property as

2(4x-11) = 10

2*4x- 2*11 = 10

8x - 22 = 10

On Adding 22 on both side

8x - 22+22 = 10+22

8x = 32

On dividing both side by 8

\frac{8x}{8}  =  \frac{32}{8}

x = 4

PLEASE help! BRAINLIEST to correct answer!
BlackZzzverrR [31]

Step-by-step explanation:

sec(x) = 1/cos(x)

and therefore, it behaves accordingly.

the minimum of cos(x) is the maximum of 1/cos(x).

it does not have any x-intercepts. for cos(x) = 1 (max) we get 1/1 = 1 for sec(x), which is the minimum.

mirrored to this, cos(x) = -1 gives us also -1 for sec(x).

sec(x) = 1/cos(x) can never have a result between -1 and +1.

cos(0) = 1, so also sec(x) = 1, and therefore (0, 1) is the y-axis intercept.

at every pi (beginning at 0) there is a horizontal tangent, but not an asymptote. the (vertical) asymptotes happen at every pi beginning at pi/2 and -pi/2.

therefore, only the third and fourth answer options are correct.
